The short--snout icefish, Salangichthys (Neosalanx) jordani Wakiya Takahasi,is one of commercial fishes in Tai Hu Lake. Experiments on artifical fertilization ofthe fish were carried out in spring of 1981 and 1983.The ripe egg of the icefish is spherical, on the egg membrance there bear 8--13slender filaments radiating around the margin of micropyle, the filament are dichoto-mously divided directing to the opposite pole of the micropyle and connected each otherto make a network covering almost the entire surface of the egg. The eggs are strongsticky, the spawned eggs attach on the submerged plants and other matrix in thewater. The diameter of swollen egg is 0.59--0.73mm, average 0.64mm. The embryohatched out 149 hours after the fertlization, 865 prelarvae were obtained in the experi-ment. The protection of spawning ground of the icefish, especially the submergedplants is proposed.
